A protocol used in IPsec to provide data integrity, authentication, and anti-replay services. A protocol suite used for securing communications by authenticating and encrypting each IP packet of a communication session.
A protocol used to establish security associations in IPsec, allowing the negotiation of keys and algorithms for secure communication. A protocol in IPsec that provides confidentiality, data integrity, and authentication of the packets.
An IPsec configuration where the entire IP packet is encapsulated within another IP packet for secure communication between networks. An IPsec configuration where only the payload of the IP packet is encrypted and authenticated, while the original IP header remains intact.
A security tool that monitors network traffic for suspicious activity or security policy violations. A set of security parameters negotiated between two IPsec peers for secure communication, including encryption algorithm, integrity algorithm, and keys.
